Who first appears at the beginning of Scene 4?

The shepherd who worked for Laius is the first to appear at the beginning of Scene 4. This character plays a crucial role in the unfolding of the play's central mystery. His arrival is significant because he holds vital information about Oedipus's past, particularly concerning the events surrounding the king's birth and the prophecy that haunts him. The shepherd previously took part in the events that led to Oedipus being saved after his birth, and his testimony will ultimately reveal the truth about Oedipus's identity and his connection to the earlier tragedies that unfold.

This choice effectively highlights the theme of fate versus free will, as the shepherd's recollections will lead Oedipus closer to the truth about his origins and the fulfillment of the prophecy. His significance continues to resonate throughout the play as Oedipus's quest for truth uncovers the horrifying reality of his actions and their consequences. The interactions with this character are pivotal as they deepen the tragic elements of Oedipus's story.
